Traditional alloy lens blocking 

The Layoutblocker-PRA  fits best in traditional production environments where alloy is still be used. In general, labs of this kind are less industrialized. These labs can profit from Layoutblocker-PRA.

  • Basically, the manual ophthalmic blocker is the best solution when high throughput alloy blocking is needed.
  • 2 blocking stations provide precise, fast and easy blocking for highest productivity.

Alloy Blocking Technology

  • Furthermore, process data can be entered from a host computer via optional bar code scanner or manually.
  • In addition, control software automatically checks the correct selection of the block-ring.
  • Layoutblocker-PRA features an optical lens recognition system: a “go/no go” indicator alerts the operator when the lens is correctly positioned.

Easy to use

  • The system automatically adjusts prism angle, prism base and the axis of the blocking chuck.
  • Finally, the precise auto-fill feature creates a consistent alloy wafer on every lens – minimizing operator intervention.
